Who we support

As a cybersecurity provider, we are committed to supporting non-profit organisations that promote learning, education, and competition in the area of cybersecurity and safe online practices for young people, schools, and colleges.

We recognise the importance of cybersecurity awareness and education in today’s digital world, and we believe that non-profit organisations play a crucial role in promoting this cause. By supporting these organisations, we aim to create a safer and more secure online environment for everyone. We provide technical and financial assistance to these organizations to help them achieve their objectives, such as organising cybersecurity competitions, developing educational materials, and providing training to educators and students.

We believe that by empowering young people with the knowledge and skills they need to stay safe online, we can make a positive impact on the future of cybersecurity and create a more secure digital world for generations to come.

Cybersafe Kids

CommSec supports the awareness of practical online educational programmes for children though our sponsorship of Cybersafe Kids. Our cyber security professionals regularly deliver talks and training to Irish schools on behalf of Cybersafe Kids.

Zero Days

Zero Days Security organise and promote cyber-security challenges, commonly known as capture-the-flag (CTF) events. Their aim are to promote, develop and encourage participation in CTF events in Ireland. Each Year they run a number of our own events including the Irish College’s Cyber-Security Challenge, Cyber-Schools, and Irish team selection and training for the European Cyber Security Challenge.

work life balance and sustainability

As an employer, we are committed to promoting responsible working culture through hybrid working and the use of anchor days for collaboration and innovation in the solutions we provide to our customers. With hybrid working, our employees have the flexibility to work from home or come into the office on designated days, which not only provides a better work-life balance but also reduces the environmental impact of fossil fuels and travel.

Additionally, we believe that weekly team and group meetings provide the necessary platform for our people to work together and generate new ideas, which ultimately benefits our customers and helps us achieve our business objectives in a responsible and sustainable manner.

Workplace Inclusiveness


Our company is committed to fostering a workplace that is inclusive, diverse, and equitable.

We believe in providing fair and equal opportunities for employment and supporting individuals from all backgrounds, genders, and identities to succeed in their careers. In particular, we recognise the value of women’s contributions to the field of cybersecurity and are dedicated to supporting and empowering women to thrive in this industry. We have implemented policies and practices that promote gender diversity and inclusivity in our hiring, training, and advancement processes.

Additionally, we provide resources and support to our female employees to help them excel in their roles and reach their professional goals. By prioritising diversity and inclusivity, we aim to create a workplace culture that is not only fair and just but also fosters innovation and creativity.
